STALIN [3.7K]

Answer:

Second one

Step-by-step explanation:

They have one angle (R) in common

Also,

Angles T & S and P & Q are equal because they are corresponding angles.

RS/RT = SQ/TP

4/(4+4) = 2x/(x+6)

4x = x + 6

3x = 6

x = 2

SQ = 2(2) = 4

TP = 2 + 6 = 8

Andrej [43]

Answer:

315 cm²

Step-by-step explanation:

Given the scale factor of 2 similar figures is a : b , then

ratio of areas = a² : b²

Here the scale factor = 7 : 21 = 1 : 3 , thus

ratio of areas = 1² : 3² = 1 : 9

That is the area of the enlargement is 9 times the original, so

area of enlargement = 35 × 9 = 315 cm²
