Question

THIS IS FOR 25 POINTS

There is a pair of parallel sides in the following shape.
12
2
13
7
What is the area of the shape? __

Answer 1

54

Explanation:

two ways:

1. find the area of the trapesium

1/2(sum of parallel sides)x height

= 1/2(7+2)×12

1/2(9x12)

1/2(108)

= 54

Or

you can divide the figure into 2 parts, rectangle and triangle,

so you find the area of triangle(1/2basexheight) and then the area of rectangle (length x width)

and then add the two areas. it should also give you same answer.

let me know if it makes sense
