What is the surface area of a rectangular prism with square bases wirh measurements a= 5 cm ,b= 7cm

190 cm^2

Step-by-step explanation:

There are 2 congruent square bases: 5 cm * 5 cm * 2 = 50 cm^2

There are 4 congruent rectangular sides: 5 cm * 7 cm * 4 = 140 cm^2

Total surface area: 50 cm^2 + 140 cm^2 = 190 cm^2

the image of (6, 9) under a dilation is (4, 6). the scale factor is

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
