Answer to Problem 27PPS
Area is 25 unit2.
Perimeter is
Explanation of Solution
Given information:
Formula used:
Distance formula=
Graph:
Calculation:
The points are:
Using distance formula to find PQ, QR, RS, SP
PQ ,
Substitute values in formula,
PQ=
Solving,
PQ=
Hence, PQ is
QR,
Substitute values in formula,
QR=
Solving,
QR=
Hence, QR is 5.
RS,
Substitute values in formula,
RS=
Solving,
RS=
Hence, RS is
SP,
Substitute values in formula,
RS=
Solving,
RS=
Hence, RS is
The polygon is a square
Now,
Perimeter = sum of all sides
Substituting values,
Perimeter=
So, perimeter is
Now, to find area,
Area=
Substituting values,
Area=
Solving,
Area=
Hence, area is 25 unit2.
