Question

Having trouble please help me !!

Answer 1

213

Explanation:

Use the triangle area formula :
`(1)/(2)`×bh

b = length h = height

b = 14.8 + 5.2 h = 21.3

1)
`(1)/(2)` × (14.8 + 5.2) (21.3)

Add the numbers in the parenthesis.

2)
`(1)/(2)` × (20) (21.3)

Multiply the parenthesis.

3)
`(1)/(2)` × 426

Reduce the numbers with the greatest common factor: 2

4) 213
