Dalia’s living room is 12-feet long and 10-feet wide. Her dining room is also 10-feet wide. Write two equivalent expressions to represent the combined area of the two rooms. Show your work

244

Step-by-step explanation:

If each room is a square, then,

area of living room = 12*12 = 144 square feet

area of dining room = 10*10 = 100 square feet

so the combined area would be 144+100 = 244 square feet

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
