I think the answer is 66. But I'm not sure just try and see...!
The triangle is 28 cm. You multiple 7 x 8x 1/2.
the parallelogram is 50. the formula is A=bh ( area = base x height)
(5*3)(2*3)=(15)(6)=90
7*3=21
21*3=63
Answer:sorry homie slice
Step-by-step explanation:
Perimeter = 1020 m
let width be = X
let length be = 20 + 6 (X)
perimeter of rectangle = 2 ( length + width )
1020 = 2 ( 20 + 6 X + X )
1020 = 2 ( 20 + 7 X )
1020 = 40 + 14 X
14 X = 1020 - 40
14 X = 980
X = 980 / 14 = 70
width = X = 70 meters
length = 20 + 6X = 20 + 6 ( 70 )
= 20 + 420
= 440 meters
HOPE IT HELPED !!
