a trapezoidal lawn has upper base of 16 meters and a lower base of 30 meters. the distance between the parallel base is 10 meters. if the lawn is to be planted with bermuda grass,how many square meters of bermuda grass will be needed?​

Sagot :

The square meters bermuda grass required is 230 m².
Step-by-step explanation:
The upper base of the trapezoidal lawn = 16 m
The lower base of the trapezoidal lawn = 30 m
The distance between the two parallel bases of the lawn = 10 m
We know the formula of a trapezium is given by,
Area = ½ × [sum of parallel sides] × h
Thus, substituting the given values in the formula, we get
The required square meters of the bermuda grass to be planted all over the trapezoidal lawn is,
= Area of trapezoidal lawn
= ½ × [16 + 30] × 10
= ½ × 46 × 10
= ½ × 460
= 230 m²
