Question

Find the area of each figure in units squared and then match the figure with its area.

Answer 1

1)

the area of the given figure is,

base x height = 9.5 x 14 = 133

2)

the area of the given figure is ,

`=(1)/(2)(30+19)*16`
`\begin{gathered} =(1)/(2)*49*16 \\ =392 \end{gathered}`

thus, the area is 392

3)

the area of the half circle is,

diameter d = 11

`=(1)/(2)*\pi*(d^2)/(4)`
`=(1)/(2)*(22)/(7)*(11^2)/(4)`
`\begin{gathered} =(11^3)/(28) \\ =(133)/(28) \\ =47.52 \end{gathered}`

4)

the area of the trinagle is

1/2 x base x height

= 1/2 x 26.4 x 11

= 13.2 x 11

= 145.2
