Answer:
a) 15.625 cm²
b) 8 cm²
c) 50 cm²
d) 12 cm²
Step-by-step explanation:
a) area of a parallelogram = base x height
⇒ area of yellow shape = 1/2 x base x height
= 1/2 x 12.5 x 2.5
= 15.625 cm²
b) area of triangle = 1/2 x base x height
= 1/2 x 2 x 8
= 8 cm²
c) area of a parallelogram = base x height
area yellow parallelogram = (10 x 6) - (5 x 2) = 50 cm²
d) area of a parallelogram = base x height
⇒ area of a 1/2 parallelogram = 1/2 x base x height
⇒ area yellow shape = 1/2 x 12 x 2 = 12 cm²
