Question

The area of a right triangle is 36 cm and its
base is 9 cm. Find the length of the perpen-
dicular.

Answer 1

Answer:

8 cm

Step-by-step explanation:

let, perpendicular = x cm

base=9 cm

area = 36 sq. cm

so,

1/2×9×x=36

x=36/9×2=8

so, perpendicular = 8cm.

Answer 2

Answer:

X= 8 cm (length of perpendicular)

Step-by-step explanation:

Given that : Area of right triangle = 36cm^2

Base = 9cm

Let the length of perpendicular be X

We know the formula of right triangle,

Area of right triangle = 1/2 ( Base × Perpendicular)

• 36cm = 1/2 ( 9cm × X)
• 36cm×2 = 9Xcm
• 72cm/9cm = X
• X = 8 cm

Therefore, The length of the Perpendicular is 8cm.
