Question

Find the length of the side of a square, whose area is equal to the area of a rectangle with side 240m and 70m.

Answer 1

Area of rectangle=a*b=240*70=16800
Area of square=a^2=16800
a=root 16800= 129.61m

Answer 2

Answer:

According to the question

, Area of square = Area of rectangle

Side ^2 = 240 × 70 Side

= √(240 × 70) =

√(10×10×2×2×2×3×7)

= 20√(42)

= 20 × 6.48 = 129.60 m

∴ The length of side of the square is 129.60 m
