Question

Find the length of the side of a square
(to two decimal places), whose area is
equal to the area of a rectangle of length
18.4 m and breadth 2.6 m.​

Answer 1

Step-by-step explanation:

Area of rectangle= 2(l+b)

= 2(18.4+2.6)m

= 2×21m

= 42 m²

Area of rectangle = Area of square

42m²=42m²

Area of square= 42m²

Side of square = Side/2

= (42/2) m²

= 21m² Ans

Answer 2

Answer:

area of rectangle = l*b

= 18.4×2.6 = 44.64 m²

= area of square is s²

s²=44.64

s=√44.64

s= 6.81 cm
