Answer:
Step-by-step explanation:
From the isosceles-base theorem, the measure of the angles adjacent to the pair of congruent sides of the triangle are equal. Since the problem declares , the remaining unknown angles are equal (
). The sum of the interior angles of a triangle always add up to
.
Therefore:
.

Answer:
Area of each piece = 104
Possible dimensions are 26 cm by 4 cm, 13 cm by 8 cm.
Step-by-step explanation:
Given that:
Dimensions of the rectangular board as:
Length of the board is 10 cm longer than its width.
Width of the board = 26 cm
Length of the board = 26 + 10 = 36 cm
The rectangular board is divided into 9 equal pieces.
To find:
Area of each piece and
the possible dimensions of each piece = ?
Solution:
First of all, let us calculate the area of bigger rectangular board.
Area of a rectangle is given by the following formula:
Area = 26 36
Area of each smaller rectangle =
To find the possible dimensions, we need to find the factors of 104.
104 = 26 4
104 = 13 8
Therefore, the Possible dimensions are 26 cm by 4 cm
and
13 cm by 8 cm.
