Question

find the answer chapter square root​

Answer 1

1) Area of square = a² = 25600

a = √25600 = 160m

2) By Pythagoras theorem,

XZ = √(XY²+YZ²)

= √(100+900) = √1000

= 10√10cm

3) Let the side of the square be a then,

Area of rectangle = lb = 48×12 = 576m²

Area of square = a²

By the given conditions,

lb = a² - 100

a² = 576 + 100 = 676

a = √676 = 26m

Hence,

perimeter of square = 4a = 4×26 = 104m

4) Length of diagonal = √(l²+b²)

d = √(144+81) = √225 = 15m

I don't know the rest
