Question

The base of a triangle is 15 cm and its height is 12 cm. Find the height of another triangle if its area is doubled the area of the first triangle and base 20 cm. With solution

Answer 1

Step-by-step explanation:

Area of first triangle =1/2×b×h

1/2×12×15=90cm^2

for another triangle. A =1/2×b×h

double the first area.180cm^2=1/2×b×h

180=1/2×20×h

180/10=h

18cm =h
