Question

The base of an isosceles triangle is 12cm and its perimeter is 32cm.Find it’s area.

Answer 1

Step-by-step explanation:

2x+12=32

x=10

area =1/2×base ×height

height=✓100-36=8

area =48

Answer 2

perimeter of triangle = a+b+c

32=12+b+c

32-12= bc

20= bc

Area of triangle = 1/2 multiplied by base multiplied by height

= 1/2 multiplied by 12 multiplied by 20

= 6 multiplied by 20

= 120 cm

Therefore area of triangle is 120 cm
