Question

If W, V, and U are the midpoints of triangle SRT, find SR.

A.1.7

B.2.3 C.3.4 D.4.6    

Answer 1

The correct answer option is D. 4.6.

Explanation:

We are given a triangle SRT and we know that W, V and U are its mid-points.

We are to find the length of the side SR.

Since we know the length of the side UR, which is equal to 2.3, with the help of this, we can find the length of the side SU.

We know that U is the mid-point for the SR which means it divides it into equal lengths. Therefore, if UR = 2.3 then SR = 2.3 * 2 = 4.6.

Answer 2

The correct answer is 4.6

EXPLANATION

`|SR|=|RU|+|SU|`

Since U is the midpoint of |RS|,

`|RU|=2.3=|SU|`

U being the midpoint of RS means, it is in the middle of R and S.

So if from R to U is 2.3, then from U to S is also 2.3.

This is an implication that

`|SR|=2.3+2.3`

`|SR|=4.6`
