Question

find the perimeter of a triangle having area 80 cm s.q. and length is 10 cm ​

Answer 1

Answer:

area:-80 cm²

length:- 10 cm

perimeter:- ?

Step-by-step explanation:

first we have to find breath

hence:-

area= length x breadth

80=10 x b

therefore

b= 80/10

b=8

therefore

perimeter = 2(l + b)

= 2(10 +8)

=20+ 16

therefore

perimeter :- 36 cm
