Question

THE PERIMETER OF A RIGHT ANGLE TRIANGLE IS 50CM AND THE HYPOTENUSE IS 18 CM. FIND ITS AREA.

Answer 1

Perimeter = 50cm

Hypotenuse = 18 cm.

Let the sides be a b and c where c is Hypotenuse.

Now a + b + c = 50

a + b = 50 - c

A^ +b^ = c^

(a+ b) ^2 = (50 - c) ^2

A^2 + b^2 + 2ab = 2500 - 100c + c^2

C^2 + 2ab = 2500 - 100 ☓ 18 +c^2

2ab = 2500 - 1800

2ab = 700

ab = 350

Area of triangle = 1/2 ☓ base ☓ height

Area = 1/2 ☓ a ☓ b

Area = 1/2 ☓ 350

Area = 175 cm^2
