Question

find the length and perimeter of a rectangle of area 900 m power of 2 and the breath is 20 m​

Answer 1

First we need to find the length of the triangle,

$area \: of \: rectangle = length \times breadth \\ 900 = l \times 20 \\ l = \frac{900}{20} \\ l = 45m \\ \\ perimeter \: of \: rectangle = 2(length + breadth)\\ =2(45+20)\\=2(65)\\=130m$

Therefore, the length of the rectangle is 45m and the perimeter of the rectangle is 130m.
