What is the area of polygon QUSR (square units)
.
it is a rectangle of area 6 x 7
and a right triangle area = 1/2( 3 x 7) add these two together
Rectangle QRTU has dimensions |-4| + 2 = 6 , times |-3| + 4 = 7, so area 42.
The triangle is 3 *7, so 21/2 = 10.5
42+10.5 = 52.5
(9+6)*7/2 since 9 is base1 or US, 7 is base2 or QR, and 7 is the height or RT so the area=(9+6)*7/2=52.5.
