CHAPTER 7: AREABy: Brianna Tillery, Troy Jones, and
Silvestre Rojas
Area of parallelogram A four sided plane
rectilinear figure with opposite sides parallel.
Area = base x height
If H= 5 and B = 2 what is the area?
Area of rectangles A plane figure with four straight
sides and four right angles Area = w × l w = width l = length
Width x Length = area 3.5 cm x 6cm =
Area of squares A plane figure with four equal
straight sides and four right angles.
area = width × height
A x B = Area
If a = 15 and b = 7 what is the area?
Area of a Rhombi Is a convex quadrilateral whose
four sides all have the same length
Convex means: curving out or bulging outward
Area = B x H or Area = D1 x D2 / 2
B x h
if b = 12 and h = 5 what is the area?
If diagonal 1 = 9 and diagonal 2 = 14 then what is the area?
Area of a Triangle A polygon with three corners
or vertices and three sides or edges which are line segments
Area = ½ B x H
H= 8 and B= 13 What is the area?
Area of a Trapezoid is a 4-sided figure with one pair
of parallel sides Area = ½ x (B1 + B2 ) x H
If b1= 5 and b2= 7 and the H= 4 then what is the area?
