2.	Mraba wenye ulalo (diagonal).	Eneo la Mraba iwapo umepewa ulalo (diagonal). $Eneo =( \frac{1}{2} \times ZO \times WY) \times 2$
3.	Mstatili.	Eneo la Mstatili. $Eneo = Urefu \times Upana$
4.	Pembetatu.	Eneo la Pembetatu. $Eneo = \frac{1}{2} bh$ $b = kitako \; \; h = kimo$
5.	Pembetatu yenye kivuli.	Eneo lililotiwa kivuli. $Eneo \; lililotiwa \; kivuli= Eneo \; la \; \Delta (WXZ) \; kutoa \; Eneo \; la \; \Delta (WYZ)$ $Eneo \; lililotiwa \; kivuli= \frac{1}{2}(a + b)h - \frac{1}{2} ah$ Au $Eneo \; lililotiwa \; kivuli= \frac{1}{2} bh$
6.	Trapeza (tenge).	Eneo la trapeza (tenge). $Eneo = \frac{1}{2}(a + b)h$
7.	Msambamba.	Eneo la msambamba. $Eneo = bh$
8.	Duara.	Eneo la duara. $Eneo = \pi r^2 \; \; AU \; \; Eneo = \frac{\pi d^2}{4}$ $\pi = \frac{22}{7}, \; \; r = \frac{1}{2}kipenyo, \; \; d = kipenyo.$
9.	Nusu duara.	Eneo la nusu duara. $Eneo = \frac{1}{2} \pi r^2 \; \; AU \; \; Eneo = \frac{1}{2} \frac{\pi d^2}{4}$ $\pi = \frac{22}{7}, \; \; r = \frac{1}{2}kipenyo, \; \; d = kipenyo.$
10.	Robo duara.	Eneo la robo duara. $Eneo = \frac{1}{4} \pi r^2 \; \; AU \; \; Eneo = \frac{1}{4} \frac{\pi d^2}{4}$ $\pi = \frac{22}{7}, \; \; r = \frac{1}{2}kipenyo, \; \; d = kipenyo.$
11.	Robo tatu duara.	Eneo la robo tatu duara. $Eneo = \frac{3}{4} \pi r^2 \; \; AU \; \; Eneo = \frac{3}{4} \frac{\pi d^2}{4}$ $\pi = \frac{22}{7}, \; \; r = \frac{1}{2}kipenyo, \; \; d = kipenyo.$
12.	Sekta.	Eneo la secta. $Eneo = \frac{\theta}{360} \pi r^2 \; \; AU \; \; Eneo = \frac{\theta}{360} \frac{\pi d^2}{4}$ $\pi = \frac{22}{7}, \; \; r = \frac{1}{2}kipenyo, \; \; d = kipenyo.$
13.	Eneo lililotiwa kivuli.	Eneo la secta. $Eneo = \pi R^2 - \pi r^2\;\;AU\;\;Eneo = \frac{\pi D^2}{4} - \frac{\pi d^2}{4}$ $\pi = \frac{22}{7}, \; \; r = \frac{1}{2}\;\;kipenyo, \; \; d = kipenyo.$
