Question

if breadth of a rectangle is 5 cm and diagonal is 13 cm then find out the perimeter and area of the rectangle​

Answer 1

Step-by-step explanation:

5sq(25) + b sq =13 sq(169)

bsq =144(12)

P =2(L+W)

2(5+12)=34

please mark me in brainly

Answer 2

ABCD is rectangle

in triangle DBC

breadth is base, diagonal 13 and length is perpendicular

by Pythagoras theorem

H²=P²+B²

13²= P²+ 5²

P²= 13²-5² = 169-25 = 144

P²= 144

P=12cm

length is 12cm

perimeter of rectangle= 2(l+b) = 2× 17 = 34 cm

Area of rectangle=l×b = 12×5 = 60cm²
