Question

Find the perimeter and area of given figure. 1)Length of rectrangle is 17.8cm and breath of rectrangle is 12.5cm 2) Length of square is 16.5m. find its area and perimeter.

Answer 1

we know that perimeter of rectangle is
2(l+b)
$2(17.8 + 12.5) = 2(30.37) \\ = 60.6$
we know that perimeter of a square 4a
$4(16.5) = 66.0 = 66 \\ area = {a}^{2} = {(16.5)}^{2} = 272.25$
