Question

Fifth grade DD.8 Area of parallelograms and trapezoids 05X What is the area? Write your answer as a fraction or as a whole or mixed number. 2 rt square feet

Answer 1

We can solve this using the formula below:

`A=(1)/(2)(a+b)h`

where

A is the area

a and b are the base

h is the height

From the figure given,

a= 2

b = 5 2/3

h=4 1/3

substitute the values into the formula

`A=(1)/(2)(2\text{ + 5}(2)/(3))\text{ }*\text{4}(1)/(3)`
`=(1)/(2)(2+(17)/(3))*(13)/(3)`
`=(1)/(2)((6+17)/(3))*(13)/(3)`
`=(1)/(2)((23)/(3))*(13)/(3)`
`=(1*23*13)/(2*3*3)`
`=(299)/(18)`
`=16\text{ }(11)/(18)ft^2`
