Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. remember KFC: keep, change, flip.
a/b ÷ c/d *use KFC* = a*d/b*c
=ad/ bc
2/7 ÷ 4/5 = 2/7*5/4
=10/28
(simplify)
=5/14
Do sqrt(18^2)+26^2)). It should give you the answer.

Answer:
370 mm²
Step-by-step explanation:
The area of this figure can be calculated by taking the whole figure as a full rectangle, and consider the part that is cut out from the middle of the shape as another rectangle.
Find the area of the cut-out part and subtract from the area of the full rectangular shape to get the area of the composite figure.
=>Area of full rectangular shape:
Length = 30 mm
Width = 15 mm
Area = L * B = 30*15 = 450 mm²
=>Area of the cut-out Rectangle part:
Length = 10 mm
Width = 8 mm
Area = 10*8 = 80 mm²
=>Area of composite figure = 450 mm² - 80 mm² = 370 mm²
