Question

The area of a square is 40cm and the breadth of the rectangle is 25cm , find the length of the rectangle . Also find the perimeter of the rectangle

Answer 1

Step-by-step explanation:

ar. of square= area of rectangle

${40cm}^{2} = l \times b \\ {40cm}^{2} = l \times 25cm \\ l = \frac{40 {cm}^{2} }{25cm} \\ \: \: \: = 1.6cm$

perimeter= 2(l+b)

= 2(1.6+25)cm

= 2(26.6)cm

=53.2cm

Answer 2

Solution

side of the square is=40cm

area=40² cm²

therefore the area of the rectangle is =40² cm²

now .

the length of the rectangle is

=area/breadth

=(40²/25)cm

=64cm

perimeter of the rectangle is

=2(64+25)cm

=89×2

=178cm
