Answer:
619.5cm2
Step-by-step explanation:
Based on what you defined as the parallel sides been 26cm and 33cm and the height been 21cm.
Hence the are of trapezium is half sum of the parallel sides × height.
Expressed mathematically we have:
1/2( 26 +33) × 21 = 1/2 ( 59) × 21 = (59×21)/2= 619.5cm2
29
x=22+7
x=29
The answer should be 30x+120
300 cm²
Area of Parallelogram = base X height
area = 15 X 20
area = 300 cm²
