2. Base = 15 cm
Height = ?
Area of the triangle = 87cm ²

3. Base = 22 mm
Height = ?
Area of the triangle = 170.5 mm²

4. Base = ?
Height = 31.4 cm
Area of the triangle = 1256 cm²​

Answer 1

Answer:

1. area = 1/2*b*h

area = 1/2*23.2*16.7

= 193.72

2. 87= 1/2*15*h

h = 87*2/15

h= 11.6

3. 170.5= 1/2*22*h

h= 170.5*2/22

=15.5
