Answer 1

Given: (1) ABCD is a rectangle.

(2) CD = 6 cm

(3) AD = 8cm

To find: Area of rectangle CDEF.

Calculation: We know that,

_{Area of parallelogram = base × height}

The Area of parallelogram and a rectangle on the same base and between the same parallels are equal in area

 

Here we can see that rectangle ABCD and Parallelogram CDEF are between the same base and same parallels.

Hence,

Area of Rectangle CDEF = Area of Parallelogram ABCD 

                                         = AD × CD

                                         = 8 × 6

                                         = 48 cm²

Hence we get the result as Area of Rectangle CDEF = 48 cm²
