What’s the area of this rectangle

Step-by-step explanation:

Just multiply the two sides

1.

Use FOIL (First, Outer, Inner, Last)

2.

^ After simplifying

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
