Question

if the ratio of the base and the hypotenuse of a right angled triangle Is 4:5 an the perimeter of the triangle is 48 cm, find the area​

Answer 1

Answer:

If the ratio of base to hypotenuse

is 4:5, then the final side (upright)

will = 3. (3,4,5 triangle)

3+4+5 = 12

Perimeter = 48 cm

Base = 4/12 x 48

Base = 16 cm

Hypotenuse = 5/12 x 48

Hypotenuse = 20 cm

Upright = 3/12 x 48

Upright = 12 cm.

Area of a triangle

= 1/2(base x height)

=1/2(16 x 12)

= 96 cm^2

Hope this helps :D
