The formula for the area of a triangle is A = 1/2b x h. A = 1/2*18m*20m = 180 m2
The formula for the area of a triangle is, A = 1/2b x h, where b is base and h is height. A = 1/2(18m) x 20m = 180m2 Another way to write the formula for the area of a triangle is A = (b x h)/2, which gives the same answer. A = (18m x 20m)/2 = 180m2
Area = pi*202 = 1256.637 square m to 3 dp
18m-7+12m
The area is 157 square meters rounded to the nearest whole number.
