Question

the area of a square is 169 cm find its one side and perimeter

Answer 1

area =169
side sq=169
side =underroot 169
side=13
perimeter=4*side=4*13=52

Answer 2

Answer:

i ) side of the square (a) = 13cm

i ) side of the square (a) = 13cmii) Perimeter of the square (P)

i ) side of the square (a) = 13cmii) Perimeter of the square (P)= 52 cm

Explanation:

Let side of a square = a cm

Area of the square (A) = 169cm² /* given */

=> a² = 169 cm²

=> a² = (13cm²)

=> a = √(13cm)²

=> a = 13 cm

ii ) Perimeter of the square (P)

= 4a

= 4×13cm

= 52 cm

Therefore,

i ) side of the square (a) = 13cm

ii) Perimeter of the square (P)

= 52 cm
