Step-by-step explanation:
Step-by-step explanation:
QP = QR (given by congruent marks)
SP = SR (given by congruent marks)
US is the common side
All 3 sides of each triangle are congruent with the other triangle.
Hence by SSS congruence,
triangles QPS and QRS are congruent.

Answer:
Length of fencing needed = 4x + 45
Step-by-step explanation:
Assume;
Width of rectangle = x
So,
Length of rectangle = x + 45
Find:
Length of fencing needed
Computation:
Length of fencing needed = 2(l+b) + b
Length of fencing needed = 2(x+45+x) + x
Length of fencing needed = 2(2x+45) + x
Length of fencing needed = 4x + 45
