Step-by-step explanation:
marking angle G in front of E at left side
Area of AFEG
= Length × breadth
= AG × AF
[AG = FE]
= 12 × 6 [AF = BC - ED = 15 - 9 = 6]
= 72 cm²
Area of GBCD
= Length × breadth
= GB × BC
= DC × BC. [GB = DC]
= 6 × 15 [DC = AB - FE = 18 - 12 = 6]
= 90 cm²
Total area = (72 + 90)cm²
= 162cm²
