Question

The area of a right-angled triangle is 3/5 of the area of a rectangle. The base of the triangle is 70% of the breadth of the rectangle. If the perimeter of the rectangle is 150 cm, the height of the triangle is

• A. 30 cm
• B. 20 cm
• C. 15 cm
• D. Data Inadequate

Answer 1

The correct option is D

Data Inadequate

Let the base length and height of the triangle be `x' and `h' respectively.

Let the breadth and length of the rectangle be `b' and `l' respectively.

xh = (6/5)lb

x = 0.7b

l+b = 150

So data is insufficient.
