Question

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

Answer 1

one side of 1st square =Perimeter /4=2÷4m= 0.5m

one sede of 2nd square =P/4=2.8/4=0.7m

Area of 1st square =0.5×0.5=0.25m^2

Area of 2nd Square = 0.7×0.7=0.49

Sum of Area of both= 0.25+0.49=0.74m2

now one side of Big square =square root 0.74m

perimeter =4× square root 0.74
