Step-by-step explanation:
AO = DO
2x+3 = 5x
3 = 5x-2x
3 = 3x
x = 1
DO = 5(1)=5cm
AC = 2×5 = 10cm
BC =√10²-8²
= √100-64
=√36
=6 cm
therefore, the perimeter of the rectangle
= 2×(8+6) = 2(14) = 28 cm
That is why you have an education go to school and learn your anwer.
Answer:
hey it's you again. daniel
Radii? Please explain what that means
3(24) + 2(24) + 5.39(24) = 72 + 48 + 129.36 = 249.36 ~ 249m^2
<span>Total Surface Area: </span>
<span>(add to the above) </span>
<span>2(1/2)(3)(2) = 6m^2 (area of the two triangles) </span>
<span>6 + 149 = 155m^2 </span>
