Question

Triangle P has a base of 5 m and height of 4 m. Triangle B has a base of 5 cm

and height of 4 cm. Find out how many times greater triangle P's area is
than triangle B's area.​

Answer 1

10000

Explanation:

First convert the units of triangle B to cm.

4cm = 0.04m

5cm = 0.05m

Find the area of triangle P:

A= 1/2(base*height)

=1/2(5*4)

=1/2(20)

= 10m^2

Area of triangle B:

A= 1/2(base*height)

=1/2(0.05*0.04)

=1/2(0.002)

= 0.001m^2

How many times greater triangle P's area is than triangle B's area:

10/0.001= 10000

Answer 2

100

Explanation:

p=4 x 5 /2=10m

b=4 x 5 /2=10cm

centimeter=1/100meter
