Ex . The area of a rhombus is 144 sq . ft . , and the perpendicular height is 8 ft . ;
find the base . Dase x height = area ( Art . 59 ) . . . Base = area ; height . = 144 : 8
= 18 ft . 61 . To find the perpendicular height when the area and base are given .

Hence it follows that the area of a triangle is equal to half the area of a rectangle
having the same base and perpendicular height . Ex . In the triangle A B C , the
base B C = 8 ft . , and the perpendicular height A D = 7 ft . ; required the area .

Side 18 - Multiply the divisor, thus augmented, by the last figure of the root, and subtract the product from the dividend, and to the remainder bring down the next period for a new dividend.
Side 62 - A circle is a plane figure contained by one line, which is called the circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference are equal to one another.
Side 62 - A diameter of a circle is a straight line drawn through the centre, and terminated both ways by the circumference.
Side 49 - RULE. — Multiply half the sum of the two parallel sides by the perpendicular distance between them, and the product will be the area.
Side 53 - To find the area of a trapezium. RULE. — Divide the trapezium into two triangles by a diagonal, and then find the areas of these triangles ; their sum will be the area of the trapezium.
