Question

The perimeter of two squares are 2 m and 2.8 m. Find the perimeter of a square whose area is equal to the sum of the areas of these two squares.​

Answer 1

Answer:

108.8 cm / 1.8 m

Step-by-step explanation:

Sides of two squares = (I) 2 m = 200 cm = 200÷4 = 50 cm

(II) 2.8 m = 280 cm = 280÷4 = 70 cm

Area of these two squares=(I)50 cm =50 x 50 cm² = 250 cm²

(II) 70 cm = 70 x 70 cm² = 490 cm²

Area of the other square = 250 + 490 = 740 cm²

Side of the other square = √740 = 27.2

Perimeter of the other square = 4 x 27.2 = 108.8 cm / 1.8 m
