Answer:
'<em>We </em><u>cross</u><em> </em><u>multiplied</u><em> it'</em>.
Step-by-step explanation:
Lets first understand our proportion and re write in correct Fraction form as:
Eqn(1).
where:
and are the Numerators
and are the Denominators
Now the question sais that Eqn(1). can be written as
This is true since here:
'<em>We </em><u>cross</u><em> </em><u>multiplied</u><em> it'</em>.
<em>Cross Multiplication is used when we have equations of the form Eqn(1) where there is one fraction on the left hand side and one fraction on the right hand side, so that the Numerator of the left hand side is multiplied with the Denominator of the right hand side and similarly the Denominator of the left hand side is multiplied with the Numerator of the right hand side (like a diagonal multiplication). </em>
Answer:
87.5cm²
Step-by-step explanation:
area of trapezium = 1/2 (a+b)h
1/2 × (10 + 15) ×7
1/2 × 25 × 7
1/2 × 175 = 87.5
