Question

what is area of (a)?​

Answer 1

Answer:

54cm²

Step-by-step explanation:

we will find area of ΔAED and ABCD then add it

so in ΔAED

area of right angle triangle = 1/2 x base x height

= 1/2 x12 x 5 = 30cm²

now area of ABCD

since it is Parallelogram area =  bh

4 x 6 = 24cm²

∴ 30 + 24 = 54cm²
