8.The area of the garden in a shape of a trapezoid is 30 sq m. Its height is 4m and the length of its lower base is 9m. What is the length of its upper base?
9. A whiteboard is in the shape of a parallelogram. The whiteboard has a base of 48 cm and a height of 14 cm. Calculate the area of the whiteboard?
8.Lets say the length of its upper base is a (m)
》(9+a)×2=30
》9+a=15
》a=6m
9.
To find=Area
Base ,b=48cm
Height ,H=12cm
Area of a parallelogram=bh
=48cm×12cm
=672cm
