Question

The area of a triangular field is 1.4 hectares if one of its side 350 m they the Lenght of the corresponding altitude is

Answer 1

Answer: 40 meters

Step-by-step explanation:

Given: The area of a triangular field = 1.4 hectares

The length of the side of the triangular field = 350 m

Since 1 hectare =10,000 square meters

Therefore , the area of a triangular field =$1.4\times10,000=14,000$ square feet.

Let h be the altitude of the triangle, the area of the triangular field is given by :-

$Area=\frac{1}{2}\times h\times base\\\Rightarrow\ h=\frac{2Area}{base}\\\Rightarrow\ h=\frac{2\times14,000}{350}\\\Rightarrow\ h=40\ meters$

Answer 2

Answer:

(a) 80m (b) 800 (c) 8m (d) 40m
