Land - isosceles trapezoid

Calculate the building plot's area and perimeter in the form of an isosceles trapezoid with bases of 120m, 95m, and a height of 50m.

Correct answer:

S =  5375 m2
o =  318.0776 m

Step-by-step explanation:

a=120 m c=95 m h=50 m  S=(a+c)/2 h=(120+95)/2 50=5375 m2
x=(ac)/2=(12095)/2=225=12.5 m b=h2+x2=502+12.5251.5388 m  o=a+c+2 b=120+95+2 51.5388=318.0776 m
