Question

Determine the area of this triangle...

Answer 1

650,000 cm²

Explanation:

10x6.5=65 METERS squared. They want it in CENTIMETERS squared.

65m² = 650,000cm²

Answer 2

32.5
`m^(2)`

Explanation:

The coloured triangle with the blank triangle area =

(14m x 6.5m)÷2 = 45.5
`m^(2)`

The blank triangle area =

[(14-10m) x 6.5m]÷2 = 13
`m^(2)`

Therefore:

The coloured triangle area =

(45.5 - 13)
`m^(2)`

=32.5
`m^(2)`
