Question

The base of a triangular field is 80cm and its altitude is 45cm.What is the area of the field?

Answer 1

Answer:

1800 cm

Step-by-step explanation:

Area of triangle = 1/2 x b x h

                          = 1/2 x 80 x 45

                          = 40 x 45

                          = 1800 cm

Answer 2

Step-by-step explanation:

Given that

b=80cm (base)

h=45cm (height)

area of the field=1/2×base×height

=1/2×80×45

= 40×45

=1800 cm²
