Mathematics: ∆abc is similar to ∆pqr. ab corresponds to pq, and bc corresponds to qr. if the length of ab is 9 units, the length of bc is 12 units, the length of ca is 6 units, and the length of pq is 3 units, then the length of qr is and the length of rp is .

See the attached picture.

Since ABC is similar to PQR, the corresponding sides' ratio are same.

To find QR, we use the proportion set below:

$\frac{9}{3} =\frac{12}{QR}$

Cross multiplying and then solving gives us:

$9QR=3*12\\9QR=36\\QR=\frac{36}{9} \\QR=4$

To find RP, we use the proportion set below:

$\frac{9}{3} =\frac{6}{RP}$

Cross multiplying and then solving gives us:

$9RP=3*6\\9RP=18\\RP=\frac{18}{9} \\RP=2$

ANSWER:

QR is 4 units

RP is 2 units

so i think its 136m^2

at the bottom: 6 x 7 = 42

sides: 5 x 7 x 2 = 70

triangles : 2 x 1 / 2 x 6 x 4 = 24

42+70+24 equals to 136!! hope u understand ^^
