Question

what is the value of B for the following triangular? Remember there are 10 mm in a centimeter 3 cm^230 cm^215 cm^21.5 cm^2

Answer 1

B = area of the base

Since the base is a rectangle

Area of a rectangle = Lenght x width

Lenght = 4 cm

Width = 12 mm = 12 / 10 =1.2

B = 4 x 1.2 = 4.8 cm2
