Can some one help me answer all ten questions they are due at 10:00 I will give out brainly.
1 answer:
Answer:
perimeter of rectangle=2(l+b)
=2(13.5+7)
=2*20.5
=41
area of rectangle=l*b
=13.5*7
=94.5 inch^2
area of triangle=1/2*b*h
=9.48*4.2/2
=19.90
=19.9
perimeter of triangle=a+b+c
=(4.46+9.48+10) inches
=23.94 inches^2
to find x
7x+2=3x+18
7x-3x=18-2
4x=16
x=16/4
x=4
perimeter of rectangle=2(l+b)
=2(7x+2+12.5)
=2(7*4+12.5)
2*40.5
=81
perimeter of triangle=1/2*b*h
=7.3*6.3/2
=45.99/2
=22.99
=23 mm^2
area of a triangle=a+b+c
=s+s+s
=7.3+7.3+7.3
=21.9 mm^2
Radius=14 inc
diameter=radius*2=28 inc
circumference=2πr
=2*3.14*14
=87.92
area of ciecle=π
=3.14*(14)^2
=3.14*196
=615.44
