Question

solve step by step with the help of a diagram on paper by pen, fast! ​

Answer 1

L= 15 [L = length, B=breadth, H = diagonal ]

H=17

L^2 + B^2= H^2

15^2 + B^2 = 17^2

B^2 = 289-225 = 64

B = 8

area of rectangle = L×B = 15×8 = 120

perimeter of rectangle = 2 (L+B) = 2 (15+8)

= 2 (23) = 46
