Question

area of a square and rectangle are same. if the area of the square is 169cm2. length if rectangle is 8cm. find perimter of square and rectangle?

Answer 1

area of sq=s^2
169=s^2
root 169=s
13=s

perimeter of sq=4s
=52cm

area of sq. = area of rect.
s^2=lb
169=8b
169/8=b
21.125=b

Perimeter of rect.=2(l+b)
=2(8+21.125)
=2×29.125
=58.25cm

Answer 2

Area of square = 169cm^2
a^2 = 169
a = 13 cm

Perimeter of square = 4*13
=52cm

Area of rectangle = 169cm^2
lb = 169
8b = 169
b =21.125cm

Perimeter of rectangle = 2(l+b)
=2(8+21.125)
=2(29.125)
=58.25cm
