Question

I really need to know this answer! Please help

Answer 1

Area of rectangle = 54

Area of triangle= 18

Total area = 72

Explanation:

Area of rectangle = length × width

= 9 × 6

= 54

Area of a triangle =
`(1)/(2)` × base × height

[ Height of the triangle = 10 - 6 = 4 ]

Area of a triangle =
`(1)/(2)` × 9 × 4

= 18

Total area = Area of rectangle + Area of triangle

= 54 + 18

= 72

[ The unit should be:
`cm^(2)` or
`m^(2)` etc.; it should have the 'square'. ]
