Answer:

(a) 260 square centimeters

Explanation:

The figure consists of a 10 cm square and four congruent triangles with base 10 cm and height 8 cm. Using the formulas for the area of a square and a triangle, the total area is ...

area = square area + 4 × triangle area

area = s² + 4×(1/2bh) = (10 cm)²+ 2(10 cm)(8 cm) = (100 +160) cm²

area = 260 cm²
