10-37.

The area of a triangle is equal to (0.5)(base)(height). The perimeter of a triangle is the sum of the lengths of all the sides.

The base of this triangle is14 cm and the height is 10 cm.

Area = (0.5)(14 cm)(10 cm) = 70 sq cm

Can you find the perimeter?

If someone placed a string around the entire edge of this triangle, how long would the string have to be?

Perimeter = 25 in.+ 15 in. + 20 in. = 60 inches

Can you find the area?
