Question

2 mЗmBm7 mRight triangle is moved from a rectangle to create the shaded region shown below find the area of the shaded region T-shirt to include the correct unit in your answer

Answer 1

Given that,

Right triangle is moved from a rectangle

To find the area of the remaining region of the rectangle

Area of remaining region of the rectangle is,

`=\text{Area of the rectangle-Area of the right triangle}`

Length of the rectangle (l)=8m

Breadth of the rectangle (b)=7m

Area of the rectangle is,

`=l* b`
`=8*7=56m^2`

Base of the right triangle=2m

Height of the right triangle=3m

Area of the right triangle is,

`=(1)/(2)* b* h=(1)/(2)*2*3=3m^2`

Area of the required shaded region is

`\begin{gathered} =(56-3)m^2 \\ =53m^2 \end{gathered}`

Area of the required shaded region is 53 sq.m.
