Answer:
(C) 38 cm²
Step-by-step explanation:
Top length = 6 cm
Bottom length = 5 + 8 = 13 cm
Area
= 1/2 ( 6 + 13) (4)
= 1/2(19)(4)
= 38 cm²
Answer:
Option C that is
the right choice.
Step-by-step explanation:
Given,
A rectangle with the measures of its diagonal DF and EG.
Measure of diagonal DF = ![5x-5](https://tex.z-dn.net/?f=5x-5)
Measure of diagonal EG = ![x+11](https://tex.z-dn.net/?f=x%2B11)
Note:Diagonal length of the rectangle are same.
So DF = EG
![5x-5=x-11](https://tex.z-dn.net/?f=5x-5%3Dx-11)
Subtracting
and adding
on both sides.
We have,
![5x-x=11+5](https://tex.z-dn.net/?f=5x-x%3D11%2B5)
![4x=16](https://tex.z-dn.net/?f=4x%3D16)
Dividing 4 both sides.
![x=\frac{16}{4}=4](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B16%7D%7B4%7D%3D4)
So the value of
is
.
Now plugging the value of
,we will find the numeric value of DF and EG.
DF = ![5x-5 =5(4)-5=15](https://tex.z-dn.net/?f=5x-5%20%3D5%284%29-5%3D15)
EG= ![x+11=4+11=15](https://tex.z-dn.net/?f=x%2B11%3D4%2B11%3D15)
Both are equal DF = EG.
So x=
and the length of diagonals are equal, DF = EG =
unit.
