Question

the area of triangle.whose two sides are 12 and 15 and perimeter is 48cm.

Answer 1

Answer:

180

Step-by-step explanation:

Area : length * breadth

Area : 12 * 15 = 180

Answer 2

Step-by-step explanation:

Given:

Length: 15

Breath: 12

Perimeter:48cm

Height: H^2 = P^2 + B^2

15×15 = P^2 + 6×6

225 = P^2 + 36

P^2 = 225-36

P^2 = 189

P = 13.7

Area of Triangle: 1/2×b×h

1/2 × 12 × 13.7

6 × 13.7

= 82.2 cm^2
