Question

Diagonal of a rectangle is 13 and its perimeter is 34 find area

Answer 1

Answer:

60cm*cm

Step-by-step explanation:

Perimeter of rectangle = 2(L+ B) = 34 cm

=> L + B = 17 cm ……. (1)

Since diagonal = 13 cm

By pythagoras law

13² = L² + B²

=> 169 = (L + B)² - 2LB

=> 169 = 17² - 2LB

=> 2LB = 289 - 169 = 120

=> LB = 60

Area = 60 cm²

Answer 2

perimeter=2(l+b)=34

l+b=17

d=13

by Pythagoras theorem

H^2= P^2+B^2

13^2= (L+B)^2

169=17^2-2LB

169-289=-2LB

120=2LB

LB=60

area of rectangle =LB=60
