Question

plz give answer class 7th ​

Answer 1

$\large\underline{\sf{Solution}}$

${ \bold{ \implies{\large\underline{\sf{ area_{trapezium} \rightarrow} \frac{1}{2} (a + b) \times h}}}}$

$\rightarrow\large\underline{\sf{ \frac{1}{2} (20m + 12m) \times 8m}}$

$\rightarrow(20 + 12) \times 4$

$\rightarrow 32 \times 4$

$\rightarrow 128 {m}^{2}$

Answer 2

$\large\underline{\sf{Solution-}}$

Area if the quad(ABCD)

$\sf{ \frac{1}{2} \times h \times (DC \: + \:AB) }$

By applying the formula, we get

$\sf{ \frac{1}{2} \times 8 \times (20 + 12)}$

$\sf{= \frac{1}{2} \times 8 \times 32}$

$\sf{ = {1} \times 4 \times 32 }$

$\sf{= \: 128 {m}^{2} }$

Hence, Area of the quad(ABCD) = 128m²
