Question

the legs of a right triangle are in the ratio 3:4 and its area is 1014cm^2 . find the hypotenuse.

Answer 1

Let it's leg be 3x and 4x. Then,
according to question,
Area of right angle triangle = 1/2 × 3x × 4x
1,014 = 6x^2
1,014/6 = x^2
√169 = x
13 cm = x
Hence, first side = 3×13 = 39 cm
second side = 4×13 = 52 cm.
We know that
H^2 = P^2 + B^2
H^2 = 39^2 + 52^2
H^2 = 1521 + 2704
H = √4225
H = 65 cm.
Hence, the hypotenuse is 65 cm.


Hope it helps you.

Let it's leg be 3x and 4x. Then,

according to question,

Area of right angle triangle = 1/2 × 3x × 4x

1,014 = 6x^2

1,014/6 = x^2

√169 = x

13 cm = x

Hence, first side = 3×13 = 39 cm

second side = 4×13 = 52 cm.

We know that

H^2 = P^2 + B^2

H^2 = 39^2 + 52^2

H^2 = 1521 + 2704

H = √4225

H = 65 cm.

Hence, the hypotenuse is 65 cm.
